All values except those in column (7) have been computed by me. In column (6), the solar 'days'
given have been converted into ordinary days.
[वक्रग्रहाणां स्फुटा:]
वक्रानुवक्रकालो भुक्तिविशेषेण विज्ञेयः ॥ ११ ॥
Retrograde motion
11 c-d. The times from the beginning of the retrograde motion to its end and
the follow up period can be found by the daily motion (being negative, during
this period, and the convention regarding these).
Note: The terms vakra (retrograde) and anuvakra (follow-up at the end of retrograde) are technical.
They are eight in number according to the Sūrya Siddhānta, given by the verse:
vakrātivakrā kuṭilā mandā mandatarā samā/
tathā śīghratarā śīghrā grahāṇām aṣṭadhā gatiḥ//
The generally given reading vakrā-anuvakrā is wrong in my opinion and I have read it as vakrā-
ativakrā, and ativakrā has taken the place of anuvakrā in the verse. The expression yā vakrā sā'nuvakragā
in the next verse makes it clear.
Generally the near ones are subsumed into one another. But in the case of Mars, VM gives all
these eight and their degrees and periods. See below under XVIII. 33-34.
